. TELPHER.

SPECIFICATION forming part of Letters Patent No. 761,884, dated June '7,1904. Application filed December 3, 1902. Serial No. 133.675. (Nomodel.)

the lowering and hoisting of the bucket containing the material to becarried, and has for a 'further object means by which the circuitthrough the motor will be automatically broken and the telpher returnedtoits starting-place.

In the drawings forming part of this speciiication, Figure 1 is a Viewshowing diagrammatically one form of my invention. is a view showinganother form of contact making and breaking device. Fig. 3 is a viewillustrating tlie'reversing-switch.

Fig. 4 is a view showing the lever-arm for breaking the circuit on therise of the bucket. Fig. 5 is a diagram showing the switch and itsconnections with. tlie hoisting-motors.

A representsv a rail or track on which travels a motor B, the motorreceiving-its current from a wire C through a trolley D. The motorcarries an electric hoisting device consisting of a motor E, whichoperates a hoistingdrum F, which carries the lioisting-rope G, to

which is attached the bucket or receptacle H. I'cause the conductor C tobe provided with dead sections Oat points where it is desired to stopthe motor. Carried by the motor E is a contact-arm E', which when themotor is in the position on the line shown comes in contact with an armI, which is made of spring metal secured in any convenient manner, soplaced that the Acontact-piece J ofthe arm E will be in engagement withit when the motor reaches the position shown. The fixed end of this armI is in electrical connection through a wire K tothe main conductoroutside of the dead section. The free end of the arm I is curved upward,so as to afford ready engagement with the contact-piece J of the arm E.From this it will be seen that when the motor reaches the positionshown, the trolley being on the dead section, the motor will stop. At

l main conductor.

the same time the contactpiece J, having bearing against the arm I,current is sent through the lioisting-inotor from the main line throughwire KY to piece I, contact-piece J, arm E. The return-circuit fromthe'motor is not shown.

L represents a switch which is adapted to reverse the hoisting-motor. Inthe. position shown in full lines in Fig. l the motor will operate toraise the bucket. I provide the hoisting-rope with a disk N of a size-to engage the switch. through the hoisting-motor, the first operatioiiof the motor will-be to hoist the bucket;

but this motionmoves the switch tov the position shown in dotted lineson accountof the disk `N bearing against the switch. When the switch isso moved, it reverses the motor W hen the bucket reaches its lowestpoint, the second disk N attached to the hoisting-rope, comes invcontact with the switch and throws it into the position shown in Fig. lin full lines, upon which the motor operates to hoist thebucket. It isdesirable, however, that when the bucket rises after discharging itsload to have the current cut oilc from' the lioisting-motor and thecircuit made through the traveling motor. To accomplish this, I providethe hoist- This arm is so constructed that while it may move in theupward direction it cannot move below the horizontal. Joints of thiskind-are so well known that it need not be particularly described. Itis, however, clearly illustrated in Fig. i of the drawings. As thebucket is lowered, therefore, the arm O being Jfree to rise will passthe arm I, as indicated iii dotted Alines in Figlt. On the ascent of thebucket,

however, as this arm cannot fall below the horizontal it will engage theunder side of the arm and lift it to the position shown in dotted linesin Fig. l, thus breaking the circuit through the hoisting-motor. VInthis position of parts the disk N is just below the switch.

In order that the telpher may be automatically started, I provid e acontact-plate I), from which runs a wire Q to the dead section of theThis contact-plate Pis so The circuit being made IOO readily observed.

placed that the end of the piece I will be against it when lifted, asbefore described and as clearly illustrated in Fig. 1. This results inthe current passing from the main conductor through the wire K, piece I,contact-plate I), and wire Q, energizing' the dead section of theconductor, thereby causing' the traveling motor to move, this motorhaving' previously been reversed by any well-known meanssuch, forinstance, as that shown in the patent to Clift, No. 692,118, January 28,1902. It will be seen, therefore, that when the telpher has reached thedead section the bucket is automatically lowered and raised, and when itreaches its proper upward position the circuit through thehoisting-motor is broken. and at the same time the current is conveyedto the dead section, thus energizing it and causing the motor of thetelpher to move. The relative proportions of parts and their distancesfrom each other are of course much exaggerated, as the illustration isdiagrammatic; but the proper placing and proportioning of these partswill be obvious to one skilled in the art.

In Fig. 2 I have shown a modification of the means for breaking thecircuit through the hoisting-motor and energizing at the same time thedead section of the main conductor. In this case instead of the piece I,I provide a pivoted arm T, which is pivoted near one end. The shorterend of the arm carries a contactplate a, which when the arm is in itsnormal position is in contact with the contact-plate which is inelectrical connection with the wire K, so that in the position shown infull lines in Fig. 2 the operation as regards the hoisting-motor is thesame as heretofore described, the longer part of the arm beingsu'liiciently weighted to keep the arm in the horizontal position. Thelonger end of the arm carries a metallic contact-piece c, which isinsulated from the arm, as shown at d. Attached to the main conductorand outside the dead section is an angular metallic piece e. Thecontact-piece c is of such a length that when the arm T is in the raisedposition (shown in the dotted lines) this contact-piece c bridges thespace between the metallic piece e and the dead section of the mainline, thus conveying the current to said dead section, as will be frepresents the main switch, through which the currentis received fromany source of supply, and g represents the wire carrying the current tothe main conductor C. It will be observed thateil'her the. operation ofthe hoisting-motoror the operation of the telpher-motor may at any timebe stopped by moving' this switch.

In Fig. 5 I have shown a common form of switch which may be used with myinvention, the connections through the sameto the hoisting-motor beingshown. This switch is of ordinary form, consisting of a disk l1', havingcontact-pieces v' j, with which engage brushes Z fm f/z.

The circuit through the switch and hoistingmotor is as follows: fromconductor C through wire K, piece I, contact-piece J, arm IC, wire n,brush e, contact-piece u', brush wire /2 io and through the motors E,wire 1, brush ym, contact-piecey', ln'ush 11, wire fr to they trackwireA, thus completing the circuit. lt will be readily observed that ontln'owing the. switch as described the motor will be reversed.

IVhat I claim, and desire to secure by Letters Patent, is

1. The combination with a telpher and an electric hoisting devicecarried thereby ol means for automatically breaking the circuit throughthe telpher and establishing the eircuit through the hoisting-motor atpredetermined points, substantially as described.

2. The combination with an electric hoisting device of automatic meansfor causing the, lowering of the loaded receptacle, automatic means forreversing the motor when the load is discharged, and automaticmeansforbreaking the circuit through the motor when the receptacle has beenhoisted, substantially as described.

3. The combination with a telpher having an electric hoisting device,means for breaking the circuit through the telpher-motm' andestablishing a circuit through the hoistingmotor at predeterminedpoints, automatic means for reversing` the hoisting-motor when thebucket thereof is at its lowest point, and automatic means for breakingthe circuit through the hoisting-motor and establishing the circuitthrough the telpher-motor when the bucket has been i'aised,substantially as described.

In witness whereof I have hereunto set my hand, in the city, county, andState ol New York, this 20th day of November, 1902.
